During ventilation failure, which actions are appropriate?

During ventilation failure, which actions are appropriate?

• A. Stop non-essential operations and evacuate if necessary.
• B. Increase production to reduce air pressure.
• C. Continue all operations as normal.
• D. Switch to manual ventilation without other actions.

Answer: (A)

When ventilation fails, the priority is to protect people by reducing exposure to hazards and getting everyone to safety. Air in the working places can become unsafe quickly due to gas buildup, dust, heat, and smoke, so your first actions should minimize risk and secure safe areas. Stopping non-essential operations helps cut off additional generation of heat, dust, and gas, making it easier to manage the situation. Evacuation if necessary ensures that people move to areas with breathable air and are accounted for, which is critical when the ventilation system is compromised. Increasing production would worsen the air quality and gas levels, so it is not appropriate. Continuing all operations as normal keeps people at risk in a failing ventilation environment. Switching to manual ventilation without other protective actions leaves people exposed and does not address the broader safety steps needed (such as stopping work, securing the area, and evacuating if required). In many emergencies, manual ventilation may be part of the response, but it should be accompanied by the broader safety actions above to effectively manage the hazard.
